"My agent forgets everything between sessions" gets answered by two very different products, and the pitch decks make them sound interchangeable. They are not.

What a memory server stores

A memory layer stores what an agent remembers: facts from past conversations, summaries of earlier sessions, embeddings it can search when something in the current conversation seems related. It answers "what did we discuss before" and "what do I know about this user or this codebase." It is usually private to that agent, indexed for retrieval, and not something a teammate would open and read to find out what is going on.

What a project board stores

Develosaur stores the work itself: tasks, their order, what blocks what, who currently holds a lease on which task, and the handoff notes from the last session. It answers a different question: "what should happen next, and who is doing it." It is visible on purpose. A human opens the same board the agent is reading and sees the same plan, because the plan was never something only the agent was supposed to understand.

The tell

Open the memory layer without the agent there to interpret it, and most of the time you are looking at a vector index or a conversation transcript. Open a Develosaur board without the agent, and you are looking at a plan a person could have kept on a whiteboard: branches, priorities, a pinned head, a task marked IN-PROGRESS with someone's name on it. One is built to be queried by a model. The other is built to be read by a person.

That difference is not cosmetic. "The agent forgot the plan" is usually not a recall failure at all. The plan was never written down anywhere durable in the first place, so there was nothing to forget and nothing for the next session, or the next agent, or a teammate, to pick up. A better memory does not fix a plan that does not exist outside a context window.

Where they overlap, and where they do not

An agent keeping both is reasonable: memory for what it has learned about your preferences or your codebase, a board for what it should actually do about it. But they are not substitutes. Recalling that you dislike a particular library is memory. Knowing that "add rate limiting" is blocked on "pick a rate limiter," that it is not yet claimed, and that it is next in line behind two overdue tasks, is a plan. No amount of memory produces the second thing, because the second thing was never a fact about the past to remember. It is a decision about what happens next, made once and kept somewhere every session and every agent can find it.

How the priority order decides what is next and several agents, one plan are both about that second problem: not remembering, but planning, in a place more than one session or one agent can read. More on how the whole board works is on the how-it-works page, and more of these are on the blog.
